To all uihmn. it may concern:

Be it known that I, JOHN MURRAY, engiuser, a subject of the King of Great Britain, and a resident of Parkside Works, Dalkeith Road, Edinlinirgh,-North Britain, have invented a new and useful Improved Signature-Gathering-Machine Attachment for the Use of Bookbinders, of which the following is a specification.

I The present invention has reference to means which may be attached to signaturenatures in order from the boxes one upon'the other and carries them along to the deliveryplace. At this point the piled signatures are usually taken from the conveyer by hand. According to this'invention, however,- they are mechanically guided into an intermittently-rotating receptacle consisting of a disk There is a cover for the receptacle consisting of a stationary plate or disk situated near to the face ofthe rotating disk, but just clear of the radial bars, which can thus freel porting-disk. The when they leavethe conveyer fall into one of the compartments of the receptacle, where. they'stand on one of the radial bars now in a horizontal position. A quarter-turn of' the receptacle in the proper direction throws the signatures sidewise onto the next bar, which has passed froma vertical to a horizontal po sition, and at the same time a fresh compartment of the receptacle is'presented to the conin the second position, the

.veyer. When book, which is now knocked up by contact with the radial bars, is ready for removal to the stitching-machine. This removal may be effected mechanically by any suitable -coritrivance 'for instance, by an endless chain having atintervalspins or fingers which proj ect laterally through a slot in the receptacle cover and by their outward movement'd-raw the book from the compartment where it rests. The movementsofl the receptacle are derivedi'roni the gathering-machine and are properly synchronized therewith.

It is obvious that where no gathering-machine is employed the booksor sheets may be placed by hand in the rotating receptacle, which will transfer themto the stitching-Inachine in the manner already explained. The stitching-machine, able character, is, moreover, synchronized so as to properly deal with the work delivered to it from the rotating receptacle.

'a back elevation, Fig. 2a front elevation, Fig. 3 an end elevation, and Fig. 4 a plan view, of the gathering-machine attachment which. embodies my improvements. Fig. 5

the inside. Fig. 6 is a cross-section of the, receptacle for knocking up the signatures. Figs} 7 and'S are inside and outside views of the fixed disk, and Fig. 9 is a detail view of the rod and rack forming part of the device for imparting the intermittent movement to comprises rotate with their sup-- oosely-piled signatures the book-withdrawing mechanism.

a, is an endless conveyor which forms part of a gathering-machine of any suitable construction. (Not shown.) This conveyer receives the signatures to be bound and-delivers them intermittently to a guide 6, situated above the a movable disk 0 and a stationary disk e. The movable disk 0 has four radial barsf, arranged at right angles to one another inany convenient manner. the bars f consist of wooden blocks fitted into recesses-in the disk 0 and held elastically "against the opposite or stationary disk e by means of springs. (See cross-section, F ig. 6i)

* Intermittent rotation is imparted to the disk 0 by means of the hollow shaft 9, which receives itsrotationfrom the driving-wheel a of the gathering-machine by means of a crank-pint and a link rod is, jointed to the lever Z, pivoted to the said shaft 9 and carrying a pawl m, enga ing w th a four-toothed ratchet-wheel n, keyed on the said hollow shaft 9. For each rotation of the wheel it there will be one quar tor-rotation of the disk 0.

. The signatures passing throu h the guideinto the receptacle formed b disks 0 and e fall on their ends it on one of the radial bars f. (See Fig. 5.) 'T e rotation of the disk 0 o'nequarter-turn throws the signatures onto their backs; and thus they are knocked up in two directions. When the book is thus knocked up, the disk 0 rests, and

the book is withdrawnfrom the receptacle which may be of. any suit- In the accompanying drawings, Figure 1 is etween the is a detail of the movable disk as seen from By preference by means of a chain 0, carrying at intervals into the from behind, when the signatures are adjust',

ed, between the guides v. The intermittent movement of the endless chain is derived I from the shaft g within the hollow shaft 9 i by means of a crank s, which is connected to the rod t, to the end of which is connected a rack it. This rack engages with a ratchet device on the axle of the chain-wheel q and imparts to it an intermittent rotation, so as to move the chain intermittently in the proper direction.

\Nhile the stitching of the hook is in progress the latter remains hetween the guides v.

The stitching device may he of any suitable construction and, being well understood, needs no description. The stitching device y y is shown double. The first portion y inserts a stitch in the hook at the point 1 and the second portion y at the point 2 after the book has been moved. After stitching, the books are removed out of the guides v) to the table. i

The chain 0 while moving travels 'at high speed and projects the books from the receptacle d slightly heyond the stitching apparatus before the chain comes to rest. This heingso, fingers w .w are provided to return the books to their contact with the pins. These fingers are operated by adjustable tappets a: w, carried on the rod t, to which an endwise movement is imparted, as ahove explained. that I claim, and desire to secure by Letters Patent of the United States, is

1. A knocking-up attachment for signature-gathering machines comprising a receptacle, means for guiding the associated-signatures edgewise thereto, radial bars arranged at right angles within the receptaclefor receiving the falling signatures on edge, means for intermittently rotating the receptacle to throw the signatures edgewise onto an adjacent har and means for withdrawing the knocked-up signatures from the receptacle, substantially as described.

2, A knocking-u attachment for signature-gathering mac lines comprising a receptacle, 1r eans for guiding the associated signatures edgewise thereto, radial bars arranged at right angles within the receptacle for receiving the falling signatures on edge, means for intermittently rotating the receptacle to throw the signatures edgewise onto an adjacent bar, means for Withdrawing the knockedup signatures from the receptacle comprising an endless chain, pins extending laterally therefrom and means f or intermittently moving said chain, sutstantially as descrihed.

In testimony whereof I have signed my name to this specification in the presence of two suh scribing witnesses.
